ABSTRACT:
A threshold value T which is a little larger than voxel values of a target tissue such as bloodstream is determined. Next, a virtual ray is projected, and voxel values on the virtual ray are obtained as an array A1(original array). Then, an array A2(replaced array) is generated by the voxel values of the array A1which are equal to or larger than the threshold value T are flipped-over at the threshold value T. Then, a part of the data on the array A2, e.g., flipped-over data corresponding to the center part of the calcified region is excluded. Next, a maximum value M2on the array A2is obtained, and a value M1on the array A1corresponding to the value M2is obtained. Then, the value M1is employed as a pixel value for the virtual ray.
